The objective of this experiment was to compare the dry matter intake, nutrients digestibility, nitrogen and energy utilization of hehage among the orchardgrass(OG) pure, orchardgrass(OG)-red clover(RC) mixture and complex rnixtures(C. mix) by Korean native goat. The results obtained were surnmerized as follows: 1. Crude protein(CP) content was higher in OG-RC and C. Mix diets than in OG pure diets(P<0.05). NDF content was higher in OG pure diets than other diets(P<0.05). But ADF, Lignin contents and gross energy did not differ among all diets. 2. Dry matter intake by Korean native goat tend to be high in OG-RC diets, and low in OG pure diets. But there was no significant difference statistically. Dry matter and cellular constituents digestibilities were higher for OG-RC and C. Mix diets than OG pure diet, but CP and NDF digestibilities were no significant difference among diets. 3. The amount of nitrogen consumed amount by Korean native goat in the OG-RC diet was higher than other diets. But, due to largely relative urinary and fecal nitrogen loss, Apparrently digested nitrogen and retained nitrogen percents were not significant difference among diets. 4. The amount of energy consumed by Korean native goat in OG-RC diet was higher than other diets. But, due to largely relative urinary and fecal energy loss, digestable energy percent was lower than C. Mix diets. But.metabolic energy percent was no significant difference among diets. Therefore, there was no significant differences among sward types for the utilization of nitrogen and energy by Korean native goats.

This study was carried out to identify anatomical characteristics of the individual bones of the cranium of the Korean native goat. The pars lateralis and pans basilaris of the os occipitale were fused each other, whereas the squama occipitalis articulated with the pars lateralis, forming the sutrue. The sinus sphenoidale was formed in the corpus ossis presphenoidalis. The os prietale was observed as a single bone. In the os frontale, an fossa innominatum was found ventrolateral to the root of processus cornualis, and the orificium orbitale canalis supraorbitalis was also formed on the pars orbitalis. The meatus temporalis was formed in the medial side of the pars squama of the os temporalis. The lamina cribrosa of the os ethmoidale was membrane-like structure with many foramina. The labyrinth ethmoidalis was composed of four endoturbinalia and ten to twelve ectoturbinalia.

The objective of this study was to investigate the relationship between muscle fiber characteristics and fatty acid composition of four major muscles in Korean native black goat (KNBG). Longissimus lumborum (LL), psoas major (PM), semimembranosus (SM), and gluteus medius (GM) were obtained from five male KNBGs of 36 mon of age and subjected to histochemical analysis and to determine fatty acid composition and meat quality traits. There were significant (p<0.05) differences in fiber number percentage (FNP) and fiber area percentage (FAP) of fiber types among these four muscles. PM had the highest FNP of type I and the lowest FNP of type IIB, while SM had the highest FNP of type IIB. The highest fat content was observed in LL while SM had the lowest fat content. The proportions of SFA and MUFA were significantly (p<0.05) different among four muscles due to differences in the majority of fatty acids such as oleic (C18:1) and palmitic (C16:0) acids. The PUFA/SFA ratio was significantly (p<0.05) different among four muscles, and the highest PUFA/SFA ratio was observed in PM. Results suggested that LL and PM might be healthful because of higher desirable fatty acid value and PUFA/SFA ratio, respectively. Also, data showed that correlations between muscle fiber types and fatty acids proportion of goat muscles were reversed with those of cattle muscles.

A case of chronic cholangiohepatitis associated with Eimeria spp. is reported in a 6-month-old, male, native Korean goat. The goat died after having a 1-week history of diarrhea, anorexia and weight loss. At necropsy, numerous multifocal to coalescing, pale and mottled red foci were present throughout the liver. Histologically, numerous coccidian parasites in both sexual and asexual stages were found in the intrahepatic biliary epithelia and bile duct lumens. Based on the light microscopic and ultrastrastructural features, the parasites present in the liver were compatible with the genus Eimeria ; however, the species was not speciated.

This study was conducted to determine grazing intensity of growing Korean native goats(Capra hircus coreanae) on mountainous pasture. It was carried out to obtain basic information for improvement of mountainous pasture management and establishing feeding system of Korean native goat. A total of 20 goats were grouped by feeding systems [A mountainous pasture grazing group (Concentrated feed of 1.5% body weight, treatment 1, T1, n=10) and a barn feeding group (TMR, treatment 2, T2), n=10] to conduct study from April to September. The average forage productivity of the mountain pasture was $500.9{\pm}61.41kg/ha$. The average dry matter intake in T1 was 0.64 and the calculated grazing intensity was 21 head/ha. In productivity, when the two treatments(T1, T2) were compared, the dry matter intake was about two to three times the difference. The average daily gain per day during the experiment was 63.3 in the mountain pasture and 120 g in barn feeding. When grazing, considering mountainous pasture productivity it is necessary to increase the productivity through proper feeding. The feed costs of black goats raised by grazing on the grassland in the same period showed an average 75% reduction compared to barn feeding. As a result of this study, it can be expected that a considerable reduction of feed costs can be expected in the breeding of Korean native black goat using the mountain pasture.

Q fever is a zoonotic disease caused by the obligate intracellular bacterium Coxiella (C.) burnetii and affects wild and domestic animals worldwide. The aim of this study was to evaluate the seroprevalence of C. burnetii in native Korean goat (Capra hircus coreanae) in Gyeongbuk province, Korea, using ELISA. A total of 256 goat blood samples from 56 farms in Gyeongbuk province were collected between May 2012 and March 2013. Among them, 22 (8.6%) samples from 10 (17.9%) farms were seropositive for C. burnetii by ELISA. According to regional analysis, the seroprevalences among goat farms in eastern, western, southern, and northern areas of Gyeongbuk province were 0%, 18.2%, 36.8%, and 6.3%, respectively, showing the highest seroprevalence in the southern region. Among 22 counties in Gyeongbuk province, 10 (45.5%) counties had one or more farms positive to C. burnetii antibody. Accordingly, the seroprevalence of C. burnetii in high-risk humans and animals are constantly demanded by regional investigation.

Akabane virus is a cause of severe congenital defects, but adult animals show no signs of infection. In this study, congenital abnormalitis associated with Akabane virus infection in Korean native goat. The prevalence of serum neutralizing antibodies to Akabane virus in goat population was investigated, indicating that approximately 30% of goats in Korea were seropositive(36/120). The mother goats have the highest titers of neutralizing antibodies, as 1:128. And also there showed seropositive of Akabane virus in newborn fetus fluids. The necropsy results of newborn fetus visceral organs were appeared normal. These findings provide that Akabane virus is the ethiological agent of congenital abnormalitis and stillbirth. Our results suggest that goat in natural situations are part of the Akabane virus transmission cycle.

The morphological development of the small intestinal tissues of the Korean native goat were observed by light microscopy. Samples were taken from a 60-, 90-, 120-day-old fetus, a newborn goat and a 30-day-old goat. The results were summarized as follows; 1. In the small intestine of 60-day-old fetus, the apexes and sides of villi were covered with a simple columnar epithelium, and intervilous areas and mucosal ridges were still covered with stratified epithelium of two to six cell layers. Mesenchymal tissues formed lamina propria, circular muscle layer and serosa. The numbers of villi per cross section of the small intestine (NVPCS) were 10 to 18. 2. In 90-day-old fetus, intervillous areas and mucosal ridges of the organ were covered with simple columnar epithelium. Goblet cells in epithelium and outer longitudinal muscle layer often appeared. NVPCS were 35 to 60 and Brunner's glands were appeared. 3. In 120-day-old fetus, Brunner's glands of the duodenum and circular connection of outer longitudinal muscle layer were formed, NVPCS were 50 to 87. 4. In newborn goat, Peyer's patches were fully formed and NVPCS were 50 to 87. 5. In 30-day goat, the small intestine was fully matured and NVPCS were 81 to 102.

For the purpose to increase productivities of livestock the present investigations were undertaken in order to clarify the clinical and suclinical status of Korean native cattle, dairy cattle(holstein) and Korean native goat. Blood, feces and urine samples were collected from 247 Korean native cattle(222 adult and 25 calf), 224 dairy cattle(211 adult and 13 calf) and 142 Korean native goat rearing at Chonbuk area and analyzed for clinical, serum chemical, hematological and urinary findings. In addition, we were examined the infection rate of theileriosis, internal parasite and ring worm. The mean value for each component was calculated by statistical analysis using Excel computer program. From these investigations the following results were obtained. The mean values for RBC, PCV and etc in 433 adult cow(Korean native cattle and dairy cattle) were similar with other reports. But the mean values for MCHC of all species were lower than normal. Adult Korean native cattle and adult dairy cattle which showed hematologically normal levels were only 9.01% and 9.48%, respectively. Abnormally high values for PCV, RBC and Hb were recorded in 7.66% of adult Korean native cattle, 20% of korean native calf, 15.38% of dairy calf and 13.36% of Korean native goat. Adult Korean native cattle and adult dairy cattle which showed hematologically anemia were 4.95% and 19.43% respectively, but Korean native calf and dairy calf showed normal. Adult Korean native cattle, adult dairy cattle, Korean native calf and dairy calf which showed normal serum protein level 84.0%, 90.8%, 50% and 44.4%, respectively. In present investigations, 50% of Korean native calf and 55.6% of dairy calf were decreased serum protein values under range. These abnormally decreased serum protein values mean the shortage of antibody, and these have a possibility to occurs to pneumonia and diarrhea. From these results, the economical loss caused by pneumonia was calculated as 124,038,833 won in the KNC and 742,703,430 won in the dairy calf rearing in Chonbuk area. Calculated economical loss caused by enteritis was 56,658,690 won in Korean native cattle, 476,775,799 won in dairy calf, and the total loss amount of 533,434,488 won in Chonbuk area. Abnormally high values$(21.7{\pm}4.0mg/dl)$ for serum calcium were recorded 49.6% in dairy cattle. The mean values for serum total cholesterol were $170.8{\pm}99.8mg/dl$ in Korean native cattle, $196.0{\pm}40.6mg/dl$ in Korean native calf, $202.9{\pm}86.0mg/dl$ in adult dairy cattle and $289.4{\pm}97.5mg/dl$ in dairy calf. The infection rate of internal parsite were as follows; adult Korean native cattle: 21.2%, Korean native calf: 8.0%, adult dairy cattle: 67.8% and Korean native goat: 81.5%. The estimated economical loss caused by internal parasites infection were 1,120,855,837 won in Korean native calf, 4,994,959,405 won in adult Korean native cattle, 3,334,751,066 won in adult holstein, and the total loss amount to 9,450,566,308 won. The infection rate of theileriosis were 1.4% in Korean native cattle and 6.6% in dairy cattle. The presumed economical loss by T. sergenti infection were 154,408,482 won in Korean native cattle and 171,577,237 won in dairy cattle rearing at Chonbuk area. The infection rate of ringworm were 0.5% in Korean native cattle, 0.9% adult dairy cattle and 7.7% in dairy calf. The presumed economical loss by dermatomycophyte were 12,061,532 won in Korean native cattle, 16,895,403 won in dairy cattle, and the total estimated loss amount to 28,955,935 won a year in Chonbuk area.

This study was performed to provide the basic data for preservation and improvement of genetic resources according to finding genetic construction obtained from analysis of genetic characteristics of $\beta$-casein gene in Korean Native goat and Saanen using the PCR-RFLP. This study confirmed the amplified products of 481bp fragments obtained from the amplification of $\beta$-casein loci by PCR. The $\beta$-casein AB genotype showed 481, 284 and 197bp, and $\beta$-casein BB genotype showed 284 and 197bp fragments in Korean Native goat and Saanen. The frequencies of $\beta$-casein genotype in Korean Native goat were 6.25 and 93.75% for AA and AB and the frequencies of $\beta$-casein genotype in Saanen were 57.14 and 42.86% for AA and AB types. The frequencies of $\beta$-casein A and B alleles were 0.031 and 0.969 in Korean Native goat and the frequencies of $\beta$-casein A and B alleles are 0.286 and 0.714 in Saanen, respectively. The nucleotide sequence of $\beta$-casein gene of Korean Native goat was 97.71% higher homology with 11 nucleotide sequences difference of that of goat reported in GeneBank (M90556). Therefore, this study of molecular genetic characteristics by the analysis of genetic polymorphism and sequencing for $\beta$-casein gene should be used as basic and applying data for preservation and improvement of genetic resources in Korean Native goat breeding.
